    摘要： Catalyst Systems, processes of forming the same and polymers and polymerization processes are described herein. The process of forming the catalyst system generally includes providing a first compound including a magnesium dialkoxide and aluminum alkoxide: contacting the first compound with a first agent and a second agent to form a solution of reaction product “A”, the first agent including a titanating agent and the second agent including a first metal halide; contacting the solution of reaction product “A” with a third agent to form a solid reaction product “B”, the third agent including a second metal halide: contacting the solid reaction product “B” with a fourth agent to form a solid reaction product “C”, the fourth agent including a third metal halide: optionally contacting the solid reaction product “C” with a fifth agent to form a solid reaction product “D”, the fifth agent including a fourth metal halide; and contacting the solid reaction product “C” or “D” with a sixth agent to form a catalyst component, the sixth agent including a first organoaluminum compound.

    摘要： A video processing device receives video data and transmits the video to a display device at a new bit rate that is dynamically adjusted based on variable conditions. The new bit rate is adjusted, at least, by scaling the video and/or a residual image and may be adjusted utilizing compression functions, compression parameters, scale factor, frame rate, color space, and chroma sub-sampling. The display receives video at the adjusted new bit rate and decompresses the video in accordance with corresponding adjustments in the video processing device. Bit rate determination is based on variable operating conditions, display information, image quality, BER, packet error, SNR, desired level of compression, energy consumption, link congestion and display capabilities. Video may be scaled prior to compression. The video may comprise a frame and/or a slice. DPCM, H.264, AVC, transform compression and scaling may be utilized. The display may utilize intra-frame spatial prediction.

    摘要： A device (300) for displaying panoramic images includes an image sensor (315), a panoramic display module (345) and a display (325). The display (110, 200) displays an annular panorama view (120, 210). The annular view (120, 210) may be an incomplete annulus for illustrating a missing view angle (126) from an incomplete panoramic image. The display (200) further includes a window (220) and a high resolution display portion (240). The window (220) bounds a portion (230) of the annular view (210). The high resolution display portion (240) displays a high resolution image corresponding to the portion (230) of the annular view (210). The window (220) is movable around the annular view (210). A size of the window (220) or the high resolution display portion (240) is adjustable. A method for generating a panoramic image is also provided.

    摘要： A lens module includes a lens supporter, and a lens group received by the lens supporter. The lens supporter includes an aperture plate, a main body extending downwardly from the aperture plate and a receiving space formed by the aperture plate and the main body, the aperture plate having a light aperture, the main body having an internal surface facing the receiving space. The lens group includes a first lens abutting against the aperture plate for forming a first alignment accuracy, a second lens stacked on the first lens and keeping a distance from the internal surface of the main body, a third lens stacked on the second lens and keeping a distance from the internal surface of the main body, and a fourth lens stacked on the third lens and abutting against the internal surface of the main body.
